HTML build errors for a large project

[tobydriscoll]

As my project has become larger, building the HTML version has become unstable in a nondeterministic way. When I run

myst build --html --execute

the site is build successfully, and then the server is started up. I get the following:

📚 Built 153 pages for project in 6.5 s.


        ✨✨✨  Starting Book Theme  ✨✨✨



🔌 Server started on port 3000!  🥳 🎉


        👉  http://localhost:3000  👈


request to http://localhost:3000/upwind.json failed, reason: read ECONNRESET

In one case I got a write EPIPE error instead of read ECONNRESET. And sometimes, the build does finish successfully instead. I don't do anything other than rerun the build command.

I didn't experience any of this until the site got quite large.
